python使用turtle步骤_python图形工具turtle绘制国际象棋棋盘

利用turtle库绘制一个国际象棋棋盘

本文实例为大家分享了python图形工具turtle绘制国际象棋棋盘的具体代码,供大家参考,具体内容如下

#编写程序绘制一个国际象棋的棋盘

import turtle

turtle.speed(30)

turtle.penup()

off = True

for y in range(-40, 30 + 1, 10):

for x in range(-40, 30 + 1, 10):

if off:

turtle.goto(x, y)

turtle.pendown()

turtle.begin_fill()

turtle.color("black")

turtle.forward(10)

turtle.left(90)

turtle.forward(10)

turtle.left(90)

turtle.forward(10)

turtle.left(90)

turtle.forward(10)

turtle.left(90)

turtle.end_fill()

turtle.penup()

else:

turtle.goto(x, y)

turtle.pendown()

turtle.forward(10)

turtle.left(90)

turtle.forward(10)

turtle.left(90)

turtle.forward(10)

turtle.left(90)

turtle.forward(10)

turtle.left(90)

turtle.penup()

off = bool(int(off) - 1)

off = bool(int(off) - 1)

turtle.hideturtle()

turtle.done()

通过函数的重用优化代码:

先建立一个UsefulTurtleFunctions.py 的文件夹

import turtle

#Draw a square

def drawSquare():

turtle.pendown()

turtle.forward(10)

turtle.left(90)

turtle.forward(10)

turtle.left(90)

turtle.forward(10)

turtle.left(90)

turtle.forward(10)

turtle.left(90)

turtle.penup()

再在test中调用它

#编写程序绘制一个国际象棋的棋盘

import turtle

from UsefulTurtleFunctions import *

turtle.speed(30)

turtle.penup()

off = True

for y in range(-40, 30 + 1, 10):

for x in range(-40, 30 + 1, 10):

if off:

turtle.goto(x, y)

turtle.begin_fill()

turtle.color("black")

drawSquare()

turtle.end_fill()

turtle.penup()

else:

turtle.goto(x, y)

drawSquare()

off = bool(int(off) - 1)

off = bool(int(off) - 1)

turtle.hideturtle()

turtle.done()

最后结果:
